WINDOW-SASH LOCK.

Application filed October 12, 1923. Serial No. 668,138.

. To all whom it may concern:

Be it known that I, ZENAS H. WILLIAMS, a citizen of the United States, residing at San Antonio, in the county of BeXar and State of Texas, have invented a new and useful lVindow-Sash Look, of which the following is a specification.

This invention aims to provide a simple means whereby one or both of the sashes of a window may be locked in a closed position or in an open postion.

It is within the province of the disclosure to improve generally Y and to enhance the utility of devices of that type to which the invention appertains.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings:

Figure 1 shows in elevation, a device constructed in accordance with the invention, parts being broken away; Figure 2 is a sectional view of the upper bearing plate and parts associated therewith; Figure 3 is a top plan of the upper bearing plate; Figure 4 is an elevation of the keeper on the upper sash; Figure 5 is a transverse section of the keeper; Figure 6 is a plan showing the keeper which is mounted on the lower sash; Figure 7 is a plan oifthe latch; Figure 8 is a sectional View illustrating the lower hearing member, the latch andattendant parts; Figure 9 is a section taken approximately on the line 99 of Figure 8.

The numeral 1 marks a Window frame comprising a lintel 2 and a stile 3. An upper sash 1 is shown and includes a top rail 5. The lower sash is marked by the numeral 6 and comprises a top rail 7.

The device forming the subject matter of this application comprises an upper bearing plate 8 shown in detail in Figures 2 and 3. The bearing plate 8 has an intermediate opening 9 and side openings 10 and 11. The

openings 10 and 11 are countersunk as shown at 12. The intermediate opening 9 is countersunk as shown at 141-. The countersink 14 is on the opposite side of the plate 8 from the countersinks 12. A reduced slot 15 extends between the opening 10 and the opening 9.

A lower bearing 16, in the form of an angle member is provided and has a horizontal inwardly projecting flange 17 supplied with an inner opening 18 and with an intermediate opening 19. In one edge of the flange 17 there is a slot 20 which is prolonged inwardly and longitudinally of the flange 17 as shown in Figure 7. A rack bar 21 is provided and has lateral teeth 22. At its upper end, the rack bar 21 is supplied with a reduced neck 23 merging into a beveled head 24:. At its lower end, the rack bar 21 is reduced to form a stem 25. Above the stem 25 there is a transverse shoulder 26in the rack bar 21, the rack bar being cut away to form a transverse shoulder 27 located above the shoulder 26.

The neck 23 of the rack bar 21 and the head 24 are inserted into the slot 15 of the bearing plate 8. The rack bar 21 then is moved transversely, until the neck 23 is in the opening 9, the head 24 being located in the beveled portion 14 of the opening 9, as shown in Figure 2. VVhen the parts are thus assembled, securing elements (not shown) are inserted upwardly through the side openings 10 and 11 of the upper bearing plate 8 to secure the upper bearing plate tothe lower surface of the lintel 2, as shown in Figure 1. The stem 25 at the lower end or" the rack bar 21 is mounted in the inner opening 18 of the flange 17 of the lower bearing 16, and the vertical depending arm of the bearing is secured to the stile 3 of the window frame, the shoulder 26 on the rack bar cooperating with the upper surface of the flange 17 of the lower bearing 16 to hold the rack bar 21 against downward movement. The rack bar 21, thus, is mounted for rotation about a vertical axis in the bearing members 8 and 16.

' A lever 28 is mounted for sliding movement and for horizontal swinging movement on the flange 17 of the lower bearing 16. The lever 28 has an elongated slot 29, receiving that portion of the rack bar 21 which is below the shoulder 27. The lever 28 is provided with a projection in the form of a pin 30, extended above and below the lever. The lever 28 is supplied with an opening 31 adapted to be brought into registration with the opening 19 in the flange 17 of the lower bearing 16, to receive a look if desired.

A lower keeper 32 is secured at 33 to the upper surface of the top rail 7 of the lower sash 6. The keeper 32 has a slot or opening 34. A beveled lip 35 projects from the keeper 32 into the slot or opening 34. The rack bar 21 passes through the slot 34, and the lip 35 conforms to the teeth 22.

The numeral 36 marks a keeper in the form of an angle member, the depending arm of which is secured at 37 to the top rail 5 ofthe upper sash 4, the keeper comprising a horizontal arm 38 which outstands from the top rail 5. The arm 38 has a SlOl or opening 39. The arm 38 of the keeper 36 is provided with a beveled lip 40 extended into the slot or opening 39. The rack bar 21 passes slidably through the slot or opening 39.

In practical operation, the projection 30 on the lever 28 is received in the slot 20 of the flange 17 of the bearing 16, as shown in Figure 9. This holds the lever 28 against horizontal swinging movement.v If additional security is desired, a padlock or the like (not shown) may be inserted through the opening 31 of the lever 28 and through the alined opening 19 of the part 17. The rack bar 21 is held by the lever 28 in the position shown in Figures 1, 2 and 5, the

teeth 22 of the rack bar cooperating with the parts 35 and 40 of the keepers 32 and 36, respectively, and the sashes 4 and 6 being held in closed position. It will be obvious, however, without specific explanation, that the sashes 4 and 6, or either of them, will be held in a partially opened position.

Rotation may be imparted to the rack bar 21 through the instrumentality of the lever 28, the projection 30 on the lever moving out of the slot 20 in the part 17. When the rack bar is rotated, as aforesaid the teeth 22 of the rack bar are moved out of engage-' ment with the lip 40 of the keeper 36, and out of engagement with the lip 35 of the keeper 32, whereupon either of the sashes 4 and 6 may he slid freely in a vertical direction. 1

When the lever 28 is swung outwardly, as aforesaid, to rotate the rack bar 21 011 its axis, longitudinal sliding movement is imparted to the lever 28, because the pin or projection 30 must traverse the locking slot 20. When the lever is swung and slid, as aforesaid, until it extends outwardly, substantially at right angles to the part 17 of the bracket in Figure 1, the inner end of the lever 28 engages beneath the shoulder 27 on the rack bar 21 and, thus, the lever is held against tilting downwardly at its outer end.

What is claimed is:

1. In a device of theclass described, a bearing adapted for mounting on a frame, a rack bar journaled in the bearing, a keeper adapted for mounting on a sash, the rack bar engaging with the keeper when the rack bar is rotated, and a lever for rotating the rack bar, the lever being slidably mounted on the rack bar for movement transversely thereof, and being supported on the bearing, the lever and the bearing having interen-' gaging elements which coact to hold the lever against movement, when the lever is slid in one direction.
